1 Application filed. April 21,

To all whom it may concern Be it knownthat I, Airnnosi'us BRIEOHLE,

This invention is especially directed to vibrating or shuttling mechanisms for paper carriages, whlch shift the carnage automatically in opposite directions alternately, on

successive operations of the driving means,

to enable entries tobe made intwo columns successively and alternately. l5

The invention is further directed to those mechanisms which cooperate witha shuttle carriage whereby to extend the usei'ulness 'of a machine of this nature, and enable it to performinethods ofcompilation more readily than heretofore,; due to the particular and novel arrangement or relationship oi the functional mechanisms.

' mech- Thus, the application of a shuttling anisml alone to the usual shiftable paper carriage of a single counter calculating ma- -chinc,results in. shifting the carriage back -a' nd forth betweentwo columns, but the 'jamounts printed lnieach column, would be collectively accumulated on the single set of counters, and the succcessivc amounts would. be printed in staggered relation in the two columns, due to the operat on of CALCULATING-MACHINE.

to render the machine more durable, as Well as to compactly arrange the parts, to avoid injury thereto, and to reduce the liability of getting out of order.

V\ these ends, I provide an alternating mechanism of strong and durable construction, arranged parallel to and adjacent the base of the machine where it does not interfere with other moving parts. This alternatingmechanism is connected to the carriage to reciprocate the latter between two columns. I

In the present instance, I have shown the alternating mechanism as being actuated from the usual main drive shaft, but it Will be understood that some "other suitable source of power may be employed. The

, means to disable the line space mechanism,

and to prevent the addition of amounts is of simple and efficient character, which antomatically operates independently of the carriage, and as an incident to the operation of the alternating mechanism.

' the linespacing mechanism synchronously I v with each operation of the machine.

- \Vhile such amachine may have its uses,

', it is desirable toprovidemeans to eliminate the action of, theline space mechalnsm when the shuttle carriage .is positioned to enable amounts to be prlnted in one 0: the columns,

7 to permit the imprint of two related amounts on the same line, although located in separate columns.

Furthermore, in many lines of work, it is [desirable to prevent thcaccumnlation of the amounts printed in one of the columns, as

i when listing car numbers and weights, check numbers and amounts. or the like, by rendering the accumulating mechanlsm; mactive When the carriage 1s posltioned to bring the column for the identifying or designating numbers, to the printmg point.

, One object of my. invention is to improve and simplify, as well as strengthen, devices to accomplish the above mentioned results,

A; further object of my invention is to relieve the operator of the necessity, heretofore present, of devoting special attention or thought to the aohustment of the line space disabling mechan sm, to whlch end,

I place the line space disabling mechanism under control of the adjustable connection between the alternating mechanism and the carriage, which connection is set by the operator to effective or ineffective position. The line space disabling mechanism is placed in condition for action as an incident to effecting such connection, and is dis- ,abled, as an incident to the interruption of such connection. 7

Still another olnect s to provide a most simple and effective setting means to control the operatlon of the alternating mechanism, so arranged that, without disabling or interrupting the connection between the alternating.mechanism and the carriage, the shuttling of the latter and the elimination of the line spacing operation is readily avoided by operating the setting means to retain the alternating mechanism in idle position.

This object is the more easily attained in the present instance, because there is no positive connection between the driving means and the alternating mechanism.

A still further object. of the invention is to positively lock the carriage in either of its adjustable positions when operated by the alternating mechanism, against rebound in one direction, or overthrow in the opposite direction.

Another object is to enable the operator to control the automatic non-adding mecha nism from the usual non-add key, thereby simplifying the construction and reducing the number of parts.

The above and other objects and advantages will be more fully set forth hereinafter and particularly pointed out in the claims.

Calculating machines of the Vales type are shown in U. S. patents to Vales, 797,032, August 15, 1905; lIcFarland, 842,- 232, January 29, 1907; and 880,159, February 25, 1908; Vhite, 940,766, November 23, 1909; and McFarland, 1,021,013, April 23, 1912, to which reference is directed for a more complete description.

Suflice it to say that a base 968 (Figs. 1 and 2) supports parallel side frames 967, (Figs. 1 and between which are arranged, from front to rear, a keyboard section, an accumulating mechanism, and a printing mechanism.

The keys 117 (Fig. 2) of the keyboard,

arranged in denominational rows, operate levers 116, to control similarly arranged stops 115. Depression of any of the keys 117 in a denomination, projects the corresponding stop 115 into the path of its coacting rack 310, and a latch 114 maintains the stop where adjusted. The racks 310 are each pivotally mounted on their individual front and rear supporting arms 312 and 311, respectively, there being as many racks as there are denominational rows of stops. The front supporting arms 312 of the several denominational racks, are journaled on a cross shaft 300 having its hearings in the side frames 967 and the several rear supporting arms 311 are journaled on a cross rod 301 mounted in the side frames.

A restraining and restoring rod 205, carried by a series of parallel fingers 265" projecting from a rotatably supported cross bar 265, normally lies in front of and in contact with the front supporting arms 312, to hold the racks 310 in their retired or home positions against the tension of their individual drive springs 383, which springs are connected at their opposite ends to the rear supporting arms 311 and to the restraining and restoring rod 205, respectively.

A main drive shaft 200 journaled in the side frames 967, carries an arm 210 fixed thereto, and a wiper 256 on the arm 210 projects into and traverses a cam slot 220 in a crank 220 secured to the cross bar 265.

A main restoring spring 285 connected with the main drive shaft, normally holds the latter in its home position and through the arm 210, wiper 256 and crank 220, maintains the restraining and restoring rod 205 against the front arms 312 to prevent the advance thereof.

Turning the main drive shaft 200 forwardly, as by means of a handle 210, against the tension of the restoring spring 285, causes the wiper 256 to traverse the cam slot 220 to rock the crank 220 and cross bar 265, and withdraw the restraining and restoring rod'205 from in front of the front supporting arms 312, thereby further tensioning drive springs 383, and freeing the supporting arms for advancement.

The arms 311, 312 rock forwardly under the tension of their drive springs as the restraining and restoring bar is withdrawn, advancing the racks 310, until the forward ends of the racks contact the projected stops 115, or the rack detents 221 in those denominations wherein no stops have been projected. The stops, when projected, displace their denominational rack detents 221 which normally lie in the paths of the racks, and are j ournaled at their forward ends on a cross shaft 202. j

The main drive shaft is released at the end of its forward stroke, to the action of the restoring spring 285, which reverses the direction of rotation of the shaft to return the parts to their positions of rest, and during such return stroke, means (not shown, but common tothe Wales machine) rocks a "cross shaft 201"to press trip members 252 carried thereby, against theprojecting ears 11 1; of the latches 11 1, to cause them to release the stops 115 for restoration to idle Levers (Fig. 1) pivoted at 952 to the outer faces of the side frames 96?, sup- ;port the'opposite'ends of a counter axle 4100 extending across the racks 310 (Fig. 2).

Counters 490, each having a pinion 135 *socia'ted to turn therewith, andjournaled for independent rotation on the axle, are adapted to engage and disengage the racks .310.

Mechanism to effect these results, includes counter-disengaging props 319 (Fig. 1) pivoted at their upper ends to the levers 322,

and slotted'at their lower ends to embrace and rest upon the ends of a horlzontaily {extending trip rod 303 (Figs. 1 and carried in radius bars 323 (Fig. 2) journaled onthe cross shaft 300. The radius bars and triprod thus form a swinging frame.

Links 2145 connected at their rear ends to f the trip rod 303, extend forwardlyto cranks "210 212 onthe main drive shaft 200. The trip rod 303 swlngs 111 an are about the fshaft as a center, and the main drive "shaft, when inits home position, retains :the trip rod at the upper rear end of its path of travel, wherein the props 319 sup- ;"port'the levers 322 and the axle 400 in their raisedpositions, to hold the counters 190 and pinions '435 out of engagement with the f racks 310. r r p 'lhetrip'rod 303, because of its positive connection with the drive shaft 200, advances in a descending are on the forward stroke of the maindrive shaft, and withdraws its support from the props 319, le-

' vers 322 and axle 100. This would operate [to lower the counters 190 into engagement with the racks310 at the outset of the forward stroke of the main drive shaft prior to the advance of the racks 310, and to posh their-racks.

The trip rod 303 continues ts travel along descending forward are, and idly traverses [the slots in the lower ends of the props 319,

and a second set of slots formed in the for-.

ward ends of bridle links 321, the rear ends of which are connected to the legs 310, to afford time for the advance of the drive racks 310, as heretofore explained.

As the trip rod approaches the forward end of its travel, it contacts the outer end walls of the slots in the bridle links 321 to trip the legs 316, thus depriving the coun ters 490 of support, and the counters or their pinions 435, drop into mesh with the racks 310 after the latter have completed their advance, and substantially at the same time that the main drive shaft 200 completes its forward stroke.

The main drive shaft, during its returnstroke, causes the arm 210 to retrace its path along the cam slot 220 to force the restraining and restoring rod 205' against the advanced supporting arms 312 to retire the racks to their normal positions, and the racks, during such retirement, turn the counters 190 engaged therewith, to register thereon an amount corresponding to the values of the denominational. keys de pressed.

Meanwhile, the trip rod 303 is idly retracing its path along a rearwardly inclined arc, until, near the end of the return stroke of the main drive shaft, and after the racks 310 have completed their operation of the counters, the trip rod contacts the upper end walls of the slots in the disengaging props 319 to lift the latter with the lovers 322 and counter axle 100, to thereby disconnect the counters 4:90 from the retired racks 310. The legs 316 ascend with the counter axle 1400 until their feet316 clear the steps 958, whereupon springs 385 (Fig. 1) snap the legs and feet into alinement with the steps.

To provide means whereby to list the various amounts set up on the keyboard, as well as to print totals and Subtotals accumulated on the counters 490, the rear supporting arms 311 (Fig. 2) have rearward extensions 311. which swing up and down, as the supporting'arms rock forwardly and hackwardly. Links515'connect the respective extensions 311 with individual typecarriers 5141-, a. vertical row of types 501 corresponding to the related rowof keys 117, being supported in the head of each type carrier. The intervals between the lief;- set stops 115 bear a predeterminedrelation to the intervals between the centersofthesuccessive types 561 so that the arrest of the racks 310 on their advance, positions the -hammers 510, journaled on a cross'shaft'500,

in set or retracted position. Tripbars 513 under the influence of springs 583, and-controlled by the rear extensions 311 ascend with the rear extensions to release the corresponding individual hammer latches 511.. A universal latch 5 18 fixed on a shaft 502, continues to retain the released hammers retracted until the extensions 311 have completed their positioning strokes to locate the proper types 561 at the printing line, after which the universal latch 518 is lifted by the usual Wales means (not shown), to release the hammers 510 to the action of their tensioned drive springs 580. The hammers strike firing pins 562 and drive the latter against the positioned types to effect the imprint thereof on the paper held by a platen 2094.

Means (not shown) controlled by the main drive shaft 200, operates during the return stroke of the main drive shaft 200 to re-cock the hammers 510, the universal latch 518 returns to effective position, the racks 310 upon their retirement, lower the extensions 311 with their type carriers 514, and the trip bars 513, the latter freeing the individual hammer latches 511 for effective operation.

Carriageways 2067 extending across and connecting the rear ends of the side frames 967 to which they are secured, accommodate between them, a. carriage slide 2065 2, 6, S and 0) adapted to travel back and forth. Braces 2067 connect the ways to afford I strength and rigidity thereto.

A shaft 2004 ournaled in end plates 2010 fastened to the carriage slide 2065, supports the platen 2094 for rotation.

Line spacing mechanism to turn the platen, includes a reciprocatory thrust bar 2026, (Fig. 1), the forward end of which is connected to a brace rod 302 connecting the radius bars 323, and forming a part of the swinging frame which the main drive shaft oscillates. The rear end of the thrust bar 2026 terminates in a foot 2026" which, when the thrust bar is at the rear end of its travel, as in Fig. 1, contacts a transversely extending line space bail comprising a rod 2002 supported in arms 2016 having trunnions 2053 (best shown in Fig. 8) ournaled in the respective end plates 2010 of the carriage. A feed spring 2486 (Fig. 8) presses the universal line space rod toward the foot 2026*. An operating bell crank 2016 (Fig. 2) fast on one of the trunnions 2053, pivotally sup ports at 2033, an upwardly projecting line space pawl 2014, adapted to engage and turn a ratchet 2020 fixed to the platen shaft 2004. The thrust bar 2026, by retaining the universal line space rod 2002 in its retracted or rearward position, holds the line space pawl 2014 out of contact with its ratchet 2020 to enable the platen to be manually turned in either direction.

The main drive shaft, on its forward; stroke, draws the swinging frame 323, 303 forwardly, and with it the brace rod 302, to

withdraw the thrust bar 2026 relatively to the universal line space red 2002. The feed spring 2466 causes the rod to follow the thrust bar, thereby swinging the supporting arms 2016 forwardly and rocking the operating bell crank 2016 and line space pawl 2014 to draw the tooth of the pawl idly over the ratchet preparatory to taking a bite thereon.

The swinging frame restores during the return stroke of the main drive shaft, and forces the rear end of the thrust bar 2026 against the advanced line space rod 2002 to rock the latter back to its home position against the tension of the feed spring 2486. The line. space rod, as it swings rearwardly, engages the line space pawl 2014 with the ratchet- 2020 and turns the latter and the platen to feed the paper in line spacing direction.

The carriage is longitudinally adjustable in column spacing direction across the machine, to bring one or another of the columns to the printing point. Such adjustment or cross tabulating feed may be accomplished manually or automatically. Tabulating stops 2018 (Fig. 2) adjustably secured to a toothed tabulating bar 2092, each carry a stop projection 2018 adapted to contact an abutment 2091 fast on one of the carriage rails 2067 to hold the carriage in any of its adjusted positions. Trunnions 2056 (Fig. 8) and 2093 (Fig. 1) respectively, secured to the opposite ends of the tabulating bar 2092 turn in the end plates 2010 of the carriage, the trunnion 2056 projecting through its end plate and carrying a release lever 2022 (best shown in Fig. 2) to enable the operator to rock the tabulating bar against the tension of a spring 481. (Fig. 3) to withdraw the active stop 2018" from engagement with the abutment 2091 and slide the carriage in either direction to bring any selected column to the printing point opposite the type carriers 514. A slot 2022 (Fig. 2) in the release lever 2022 embraces the platen shaft 2004 to limit the throw of the release lever in either direction. The spring 481 restores the tabulating bar with its stops to effective position upon the removal of pressure from the lever 2022 To print the accumulated amount on the counters and clear the latter, the operator depresses a total key 327 (Fig. 1). A latch 326 releasably connects the total key with the forwardly extending arm of an angular set lever 317 fast on the left hand end of the cross shaft 300, a somewhat similar lever, not shown, being fastened to the right hand end of the shaft. Links 315 connect the upper arms of the respective set levers with the corresponding detaining legs 316. Depressing the total key 327 rocks the set levers 317 b to draw the links 315 forwardly and displace the legs 316 relatively to their steps 958 The' set lever 317 carries a keeper stud adjusted, against the tension of a restoring spring 382.

The upwardly extending arm of one of the set levers 317", has a loose connection 359 with a slide 320 having an inclined slot 320 to accommodate a projection 251 on a crank 222 fast on the protruding end of the cross shaft 202 on which the rack detents 221 are journaled.v Similar cranks 222 (Fig. 2)

fast on the shaft adjacent the inner faces of the side frames 967. support a cross rod 204 extending beneath the series of rack detents 221. The set lever 317, when rocked by the key 327, advancesthe slide 320 to cause the projection 251 to ride up the inclined slot 320 and rock the shaft 202 to press the cross rod 204 against the rack detents 221 and raise the latter out of the paths of their corresponding racks 310. j

The main drive shaft, as usual, at the outset'of its forward stroke. swin s the trin bar, 303 downwardly and forwardly, and the detaining legs 316 being displaced, the counters, 490 drop into mesh with their racks prior to the advance of the latter.

The main drive shaft also withdraws the restraining and restoring bar 205 from in front ofthe supporting arms 312, and tensions the drive springs 383, which advance the racks 310, owing to the displacement of the rack detents 221. The racks turn the counters in a direction reverse to that in which they turn when accumulating amounts, until the counters are arrested in their zero positions in a manner common to the ales machine and not herein shown.

'The advance of the racks 310 positions, at

the printing line, those types 561 which coring arms of each ofthe set levers 317 b (Fig.

1) .carryjthrustistuds 355' (Fig. 1) adapted,

when the set levers are rocked by the depression of the total key 327, to'clear, and lie infront of, shoulders 314 formed on the forward ends of thrust links 314, whose rear ends are connected to theupwardly extending arms of lifting bell cranks 313 journaled on the outer ends of the cross shaft 301. The remaining arms of the lifting bell cranks extend forwardly behind the legs 316 to lie adjacent inwardly projecting studs 357 on the legs.

As the main drive shaft completes its for ward stroke, the inclined rear end of the arcuate rib 217 on the quadrant clears the keeper stud 354 on the set lever 317*, whereupon the spring-382 operates to partially re store the set levers to their normal positions.

The thrust studs 355 on the upper arms of the set levers contact the shoulders 314* on the thrust links 314 to rock the lifting bell cranks 313 rearwardly and bring their forwardly extending arms against the lifting studs 357 on the legs 316. The restoring spring 382, however, is too weak to overcome the weight of the counters 490 and connected parts, and hence the keeper stud 354 remains in the path of return of the inclinedrear end of the locking rib 217.

The main drive shaft, at the beginning of its return stroke, presses such inclined rear end of the locking rib 217 against the keeper stud'354 to force the latter upwardly to normal position, together with the set levers 317 which, in turn, forcethe thrust links 3 4 farther rearwardly to rock the lifting bell cranks 313. The'bell cranks raise the legs 316 to disengage the counters 490 from their drive racks 310, after which the racks and type carriers 514 retire idly to their positions of rest, and the trip rod 303 swings the counter-disengaging props 319 back to normal effective position. Release studs 361 on the props displace the thrust links 314, as the props return to enable the lifting bell cranks 313'to restore to idle position.

In case the operator desires to print the amount accumulated on the counters, and retain the amount on the counters for further additions thereto, it is only necessary to hold the set levers 317 against release at the end of the forward stroke and until the main drive shaft on its return stroke, re-

stores the arcuate rib 217 to position over the keeper stud 354.

This is accomplished in the present in stance, by depressing a sub-total key 327 (Fig. 1) having a foot 327 overlying the forwardly extending arm of the set lever 317*, to rock the arm downwardly, as in totaling, a lock (not shown) operating to maintain the. sub-total key depressed until near the end of the return stroke of the main drive shaft. By. retaining the set levers 317 where adjusted, during the return stroke of the main drive shaft, the thrust cranks 313 remain idle, thereby permitting the counters l90 to remain engaged with the racks 310, which, on the return stroke, operate, as in adding operations, to again register the total amount on the counters.

In such sub-totaling operation, the counters are disengaged from their racks at the end of the return stroke, in the same manner as in adding operations.

Many details of construction and opera tion have been omitted from the foregoing explanation, information regarding which may be found in the patents heretofore mentioned, the various devices hitherto set forth constituting a part of my invention only in so far as they are combined with the novel features now to be disclosed.

It will be remembered that the swinging frame, including the radius bars 323, trip rod 303 and brace rod 302, oscillates forwardly and backwardly synchronously with the forward and return strokes of the main drive shaft 200, which shaft positively operates the frame through the link connec ticns 214, and cranks 210 212.

To mechanically effect the reciprocation of the paper carriage between two columns successively and alternately, I conveniently utilize the swinging frame as a driving or actuating medium, to which end, I apply depending actuating arms 1, 1 to the frame, the arms constituting extensions of the radius bars 323, to sweep forwardly and backwardly in planes parallel with and adjacent to the side frames 967. The trip rod 303 passes through the actuating arms 1, 1' intermediate their ends, (Figs. 2 and 4:), the upper ends of the arms being slotted to fit about the cross brace 302.

An alternating member or rocking beam 2 (Figs. 2 and lies in a plane parallel with and across the base 968, the member being pivoted at 3 (Fig. 3) intermediate its ends to a pedestal 968 (Fig. 2) projecting upwardly from the base. The pivot terminates in a cap a (Fig. 3) overlying the rocking beam 2 to maintain it in a horizontal plane, and prevent its tilting, as it rocks from one to the other end of its path.

Substantially triangularly-shaped tappets 5, 5 are pivotally secured at G and 7, re spectively, to the opposite ends of the beam or alternating member 2, the pivots being located approximately centrally of the tappets. A bar 8 extending between and pivo tally connected to the rear ends of the tappets 5, 5 at points eccentric to the pivots 6 and 7, operates to transmit movement from either tappet to the other, to enable them to turn simultaneously in clockwise or counterclockwise direction on their respective pivts 6 and 7, until the forward face 5 of one r the other of the tappets 5 strikes coacting stop 9 on the rocking beam to arrest the tappet. Arrest of either tappet operates through the connecting bar 8 to arrest the other tappet.

It will be noted that the opposed tappets assume an alternately effective relation, that is, when one of the tappets (as the tappet 5 in Fig. 3) has been arrested by its stop 9 at one limit of its clockwise travel, at which its outer free end forms a prolongation of the adjacent end of the rocking beam 2, ex tending into the path of its corresponding actuating arm 1, the opposite tappet 5 has been swung forwardly in clockwise direction from a similar effective position (see dotted lines, Fig. to its retracted or idle position, shown in full lines in 3, with its outer free end or finger withdrawn from the path of its actuating arm 1.

With the tappets 5, 5 in this adjustment. the actuating arm 1 will swing idly forward. and back, clearing the adjacent end of the rocking beam 2. It will be noted that thereis no positive or direct connection between the actuating arms 1, 1 and the alternating mechanism, and also that the planes of travel of the actuating arms are at right angles to the plane of operation of the alternating member.

I have contrived to automatically adjust the tappets separately and alternately from and to their effective positions, by means controlled by the alternating member 2, itself. Thus, a switch lever 10 is preferably pivoted intermediate its ends at a point 11, (Fig. on the pedestal 968 behind the pivot 3 of the alternating member. The pivot 11 divides the switch lever 10 into long and short arms. the shorter arm being in turn pivoted to the alternating member 2 by a slot and pin connection 12 between and in line with the pivotal supports 3 and 10 of the alternating member and switch lever. re spectively, when the rocking beam 2 lies intermediate the ends of its stroke, at which time the switch lever 10 lies at substantially right angles to the rocking beam.

It will thus be seeirthat the radii 3, 12. and 12, 11 constitute a toggle, and that the passage of the pivotal connection 12 from one limit of its path to the other across the dead center between the pivotal points 3. 12, 11, operates to switch the longer arm of the lever 10 from side to side. Ilence. looking from the front of the machine, if the left hand bran h of the rocking beam 2 swings rearwardly in clockwise direction, it will throw the shorter arm of the switch lever 10 toward the right and swing the longerarm of the lever toward the left, and vice versa. Divergent springs or flexible links 13.41 1 (Figs. 2 and 3) connect the lon 'er arm of the switch lever 1.0 with the connecting bar 8 on opposite sides of its center. The springs 13, it may be conveniently connected to'posts 15 depending from ears 16 formed at opposite ends of the tappet bar '8, the ears' 16 affording clearance for the posts 15, relatively to the rocking beam,

A to insure uninterrupted travel of the tappets 5, to effective position.

The extent of throw of the rocking beam 2 in either direction is determined. by the arc of travel of the actuating arms 1, 1, which in their home positions, lie at the rear ends oftheir strokes, (Figs. 1, 2 and 3) and as one or the other of the tappets 5, 5 is always in the path of its correlated actuating arm, the rocking beam or alternating member 2 is held at one or the other of its extreme positions, when the machine is at rest.

Assuming the partsto be in the positions shown in full lines in Fig. 3, it will be seen that the actuating arm 1 is in contact with the effective tappet'fi, having rocked the alternating member 2 in a clockwise direc The tion to one of its extreme positions. alternating member, in turn, has swung the longer arm of the switch lever in a counter-clockwise direction to relax the tension on the flexible link or spring 13 and increase the tension of the opposing flexible link or spring 14 to render the latter superior to the former.

The temporarily superior spring 14, tends to shift the connecting bar 8 to the left (looking from the front of the machine) to rock the idle tappet 5 counter-clockwise to effective position, and simultaneously rock he eifective'tappet 5 in the same direction to idle position, but is prevented from so do- 1 ing by thepressure of the actuating arm 1 againstthe effective tappet 5.

The main restoring spring 285 maintains the parts in these positions until the next forward stroke of the main drive shaft, whereupon the actuatingarms 1, 1, as they advance, draw away-from the tappets 5, 5 to free the latter to the actionof the superi orly tensioned spring 141-. This spring then swings the tappet'5 counter-clockwise until its inner face 5" strikes the adjacent stop 9, at which timethe tappet lies in the path of return of itsactuating arm 1, (see dotted lines in Fig. 3), and simultaneously rocks the formerly effective tappet 5 in a similar direction, to idle position. v

The stop 9, by arresting the tappet 5, opcrates through the connecting bar 8 to arrest the tappet 5 in its idle position against further rotation under the influence of the spring 1 1-. K

The rocking beam 2 remains where adjusted by the actuating arm 1'. with its righthand end advanced beyond the left hand end, so that the newly positioned right handtapp'et 5 intercepts its ac uating arm 1, fshortly after themain drive shaft 209 starts on its return stroke. The actuating arm 1 then rocks the alternating member 2 in a counter-clockwise direction, thereby advancing the left hand end of the alternating member. The latter, in turn, swings the longer arm of the switch lever 10 in aclockwise direction to tension the spring link 13 and relax the spring link 14. The mecha nism is thus setto shift the tappets 5, 5 to their respectively opposite positions during the withdrmval of the actuatlng arms 1, 1

on the next forward stroke of the main her in first one direction and then the other;

alternately.

A tail 2 extends rearwardly from. the alternating member 2 to a point beyond the rear end of the base 968, where it is conveniently connected to the carriage-shifting mechanism. A depending fork 17 pivoted to the outer end of the tail 2", loosely embraces a wrist pin 18 projecting from a crank 19 forming part of a communicating lever 19, 20. The upper end of the crank 19 is secured. to the inner end of a hub 21 journaled on a pintle 22 extending rearwardly from a hanger 23 suspended from the lower rail 2067 of the carriage. A cross head 24, fast on the outer end of the hub 21, carries at one end a pair of laterally projecting apertured lugs 25, the lugs being spaced apart from each other to embrace a similar pair of lugs 26 projecting from the lower end of the upper crank of the communicating lever 19, 20. .Ahingc pin 27 connects the pairs of lugs, this construction enabling a movement of the upper crank 20 of the communicating lever rela tively to the lower crank 19, (see dotted lilies Fig. 9) in an arc at an angle to the oscillatory travel of the crank 19. A stop flange 20 on the crank 20 contacts the cross head. 2% to limit the travel. of the crank 20 relatively to the crank 19, in one direction.

A. separable coupling 28, 29 releasably connects the crank 20 with a bar 30 mouuted in brackets 31 depending from and trav cling with the carriage slide 2065. In the present instance, I have found it convenient to journal one member of the coupling, as

the female member 28, in theupper end of the crankfZ-t) the inner end of the female member being slotted, as. at (Fig. 3) and the outer end carrying a finger piece 33,

whereby to turn the coupling member 28 to cause the slot 32 to slidingly fit over a rib 34 formed on the male member 29 of the coupling. The male member of the coupling embraces, and is adjustable along the bar 30, a set screw 35 or other convenient means, operating to retain the male member 29 where adjusted along the bar 30.

To retain the coupling members connected, I provide the cross head 24 with a rearwardly projecting post 36 supporting at its outer end, a turn button 37 adapted to pass through a slot 38 (Fig. 8) in the adjustable crank 20, when the latter is swung on its hinge 27 to engage the male and female members of the coupling 28, 29, after which the button is turned to effective position transversely of the slot, and retains the adjustable crank in position to communicate movement to the carriage.

A spring 39 encircling an operating roll or finger 40 arranged parallel with the pintle 22 and having hearings in the crank 19 and cross head 24 of the communicating lever, is confined between the outer face of the crank 19 and a set collar 41 on the rod, and presses the outer end of the rod against the adjustable crank 20 of the lever 19, 20 to disengage the coupling members 28 and 29.

From the foregoing, it will be noted that the tail 2 of the alternating member 2, will shift from side to side in a horizontal plane on successive operations of the actuating arms 1, 1. The tail will oscillate the lever 19, 20, in a vertical plane, and the lever will communicate motion to the carriage to drive the latter back and forth alternately on successive operations of the actuating arms. The fork 17 turns in the tail 2 as the latter shifts back and forth, to prevent binding between the fork and the wrist pin 18, and the slot in the fork is sufliciently long to accommodate the arcuate travel of the pin and still maintain engagement therewith. Likewise, the female member 28 of the separable coupling 28, 29 turns in the adjustable crank 20, and slides up and down on the rib 34, as the crank 20 rocks back and forth, to permit the conversion of the oscillating motion of the lever 19, 20 into the reciprocating motion imparted to the paper carriage, without cramping.

To prevent any possible hind 'ance to the shuttling operation of the carriage in either direction, due to the engagement of any of the tabulating stops 2018 with the abutment 2091, I arrange means to hold the tabulating mechanism inactive when the carriage is to be automatically reciprocated. To this end, the manuallyoperable disabling lever 2022 carries a spring-pressed pin 42 (Fig. 8) axially slidable in a sleeve 43 carried by and projecting through the disabling lever. The inner end of the looking pin removably enters a hole 44 in the adjacent end plate 2010 of the paper carriage.

A head 45 on the outer end of the pin 42 carries a key 40 adapted to seat in a notch 47 formed in the outer end of the sleeve.

Normally the pin 42 is withdrawn and slightly rotated to unseat the key .46 and cause it to rest against the outer unnotched portion of the outer end of the sleeve 43 to retain the pin 42 in idle position and enable the spring 481 to return the tabulating bar 2092 and stops 2018 to, and hold them in, effective position.

But when it is desired to lock the tabulating mechanism in idle position, the pin 42 is turned until its key 40 registers with the notch 4'7, after which the disabling lever 2022 is rocked to shift the tabulating mechanism to idle position. The disabling lever 2022, during such operation, brings the pin 42 into registry with the hole 44 in the end plate 2010, into which hole the pin snaps to lock the parts where adjusted.

In case the operator forgets to adjust the tabulating mechanism to ineffective posiion prior to shuttling the carriage, the stop 2018 in engagement with the abutment 2091 will restrain the carriage against operation, and interrupt the operation of the machine, but no damage or injury will be effected, such restraint merely prevents the return of the main drive shaft under the influence of the main spring 285, and as soon as the tabulating stop 2018 is disengaged from its abutment 2091, the shuttling mechanism will complete its operation.

To insure the accurate positioning of the carriage at each end of its shuttling stroke, irrespective of the speed or violence with which the machine is operated, I provide automatically operable means to positively arrest the carriage upon its arrival at either end of its travel.

As one means to effectthis result, I arrange a substantially vertical strut 48, (Figs. 2, 3 and 4) through the upper end of which passes a cross rod 508 extending between the side frames, the lower end of the strut being conveniently anchored at 49 to the base 968. A hasp 50 pivotally connected at 51 to the strut extends forwardly and carries a lateral flange 50 adapted to overlie and rest upon a keeper formed by an upward extension of the pivot 7 of the adjacent tappet 5. A spring 52 presses the hasp down upon the keeper. The flange 50" is provided with looking apertures (Fig. 3) located a distance apart equal to the arcuate travel of the pivot 7, to enable the hasp to snap over the keeper when the latter reaches one or the other end of its travel. Preferably the extended end of the pivot? is reduced in diameter to enter guide slots 53 which communicate with their respective apertures 53, and are entered by the V keeper just prior to its arrival at the end of some distance behind the inclined lip 54? its stroke, to position the apertures to register with the keeper.

By looking the alternating member 2 in either of itsadjusted. positions, the hasp prevents overthrow or rebound of the carriage, which is positively connectedwith the alternating member through the communicating lever 19, 20. I V

I arrange to automatically disengage the has 'and the keeper 7] prior to the actuationof the alternating member 2 on which the keeper is-mounted, by the same means which actuates the alternating member 2, to which end, I provide'the hasp with a releaser 5% (Figs. 2, 3 and 4.) pivoted at to the hasp and bearing a lifting stud 56 projecting through a slot. 57 formed in the ha'sp. A spring 58 contacts the lifting stud 56 to yieldingly hold the latter at the upper end of the slot 57 in the hasp 50. The free end of the releaserbt projects in advance of the hasp and carriesjan inclined lip 54 lying. in the arcuate path of a trip stud 59 projecting. from the adjacent actuating arm 1' i As shown in Fig. 2, the trip stud lies forward the trip stud 59 contactin the rear 7 n b face of the inclined lip 549 an depressing thei'releaser 54 idly against the tension of it from the keeper? The overhanging lip is-ot' sui'licient length to maintain contact with the trip stud 59 until onset the actuating arms 1, 1" has had time to contact the eii'ective tappet 5, or 5 and swing the alter nating member '2 so as to displace the keeper 7 relatively to the aperture 53 which was fitted thereover, after .vhich the trip stud H59 escapes the 'releaser and permits the spring 58 topress the flange 54 or" the relcaser downupon the keeper 7 in readiness to 'slip over. the keeper when the latter reaches thefopposite' end of its travel, and lock the'parts in place.

Asw hitherto mentioned, it is desirable that the line spacing mechanism be disabled or silenced on alternate operations cit-the ma.

chine to enable two amounts to be printed on the same line," and I have contrived an extremely simple, and inexpensive means to effect this result. I

In so doing, I have placed the line space disabling mechanism under the control of the communicating lever 19, 20 and I also arrange to actuate the line space disabling mechanism by such lever.

At least two novel advantages obtain from this arrangement, one being to relieve the operator of the necessity of remembering'to depress or release any manually-operable member to set the line space disabling mechanism for operation or to render the disabling mechanism ineffective, another advantage being that the carriage can be shuttled and the line space disabling mechanism can be rendered alternately eftective and ineifective, it it is desired to print two columns of amounts, all of which are to be accumulated.

A lever 60 (best shown inFig. 7) fast on a shaft 61 journaled in ears 62 projecting rearwardly from the hanger 23, carries a check member or roll 63 shiftable into and out of thepath of-advance of the universal line space bail 2002. One arm of a bell crank lever 64. engages the inner end of the lever 60 and a spring 65 (Fig. 6) connected to the bell crank lever 64, normally holds the latter at one end of it throw against a stop 66, (Fig. 8) to retain the check member 63 in idle position.

To efiect the operation of the line space disabling mechanisnnl employ the spring pressed operating finger 40, whose outer end bears against the inner face of the adjustable crank 20of the communicating lever 19, 20. to hold the crank 20 and its separable coupling member 28, disconnected from and out of the path oftravel of the coiiperating member 29 on the carriage.

When the operator desires to list amounts alternately in two columns, he will swing the adjustable crank 20 against the tension of thespring-pressed thrust finger 40 until the members of the separable coupling 28, 29 are brought in juxtaposition and then turn the rotatable member 28 until it fits over the rib 3% on the member 29 secured to the carriage. The turn button 37 will have passed through the slot 38 in the adjustable crank 20 and the ope ator will turn the but- 65 functioning through the bell crank 64 will hold the check member 63 in idle position, as illustrated in the same figure and in Figs. 2, 3 and 9.

The carriage, in these figures, is positioned to the left, to locate the right hand column at the printing point, in which position, it remains curing the succeeding forward stroke of the main drive shaft, but upon the return stroke of the shaft, the actuating arm 1 contacts its tappet to rock the alt meml and swing the communicat lever 19, 20 to the opposite limit of its 0. .el. The lever shifts the carriage to the right to bring the left hand column to the printing point, and the operating finger 1'0 carried by the le er, impinges against the depending arm of the bell crank lever 61: to shiftthe bell crank and rock the line space disabling lever to bring the check member 13 into thepath of the universal line space bail 2002, as shown in Fig. (3. l pou the next forward stroke of the main drive shaft. the thrust bar 2024 withdraws from in front of'the bail 2002 and the spring (Fig. 8) tends to advance the bail, but the check member 63 prevents such advance and retains the bail substantially in its retired position until the thrust bar 202 on the return stroke, resumes its effective position.

As the communicating lever 19, swings back to its position shown in Fig. 8,'it carries with it the operating finger 40, thereby 3 releasing the bell crank. 04 to the action of its spring (35, which thereupon returns the check member to idle position.

In case the connection between the communicating lever 19, 20. and the carriage is effected when the lever is in the position shown in Fig. 6, the inner end of the operating finger 40 will strike the depending arm of the bell crank (ll which at that time will be held by its spring in the path of the finger with the check member in idle position. To provide for such a contin ency, the depending arm of the bell crank lever (ll is preferabl v' made of resilient material to yield inwardly when the operating finger presses thereagainst. The operator will then take an idle stroke which will shift the cominunicating lever to the opposite limit of its throw, the operating linger traveling therewith and releasing the depending arm of the bell cra. k lever which restores to position to be contacted by the operating finger Q0 on the. next operation of the machine. 0

in classes of work wherein it is desired to print a designating number Or other indicia. and an amount, on the same line but in different columns, the designating number andthe amount beingprinted in successive operations of the machine, it is customary to render the accumulating mechanism ineffective when printing the designating indicia.

I have devised an extremely simple and easily operated means to automatically disable the accumulating mechanism on alternate operations of the machine, and one which because of the few parts employed, is not readily liable to get out of order. And in so doing, I have contrived to utilize the usual manually-operable non-add mechanism of the Vales machine, with such changes as will enable it to be automatically operated.

In the Wales machine, as shown in U. S. patent to McFarland, 1,024,013, above mentioned, a cross shaft 404 (Figs. 1 and 2) journaled in the opposite side frames 96?, carries hooks or restraining members ll? adapted to swing beneath the projecting ends of the counter-supporting axle l0) when the latter is in its normally elevated position, to prevent the axle and the counters 490 from engaging the racks all). N01 mally the restraining members 417 lie in idle position (Figs. 1 and 2) out of the path of the counter-supporting axle.

Depression of a key directly pivoted to a rearwardly extending arm fast on the rock shaft supporting the restraining hooks, turns the shaft to swing the hooks to effective position. And by locking the key in depressed position, successive amounts might be printed without being accumulated.

In the present invention, however, in order to permit the hooks or restraining members M7 to be automatically displaced while the key 424 remains in depressed position, I provide a spring link (57 (Fig. 2) to connect the key "A with an arm fast on the shaft 404. Depressing the key ten sions the spring to rock the restraining members 417 to effective position.

A notch 4:24; on the keystem engages the edge of the slot in the usual casing inclosing the machine, indicated at 1065, through which the key projects, to retain the nonadd mechanism effective. Releasing the key lQl relieves the tension of the spring link 67 to enable a spring 481 connected by a link 69 with one of the restraining hooks ll"? to retire the restraining hooks to idle position.

I contrive to render the non-add. mechanism automatically effective and incll'ective alternately on successive operations of the machine, to relieve the operator of the necessity of remembering to manually depress and release the key 424, as follows:

Locking the key 424 in depressed position, maintains the spring 67 under tension to overcome the restoring spring 4181 and hold the restraining members 417 effective.

To restore the restraining members to ineffective position, notwithstanding the continued depression of the nonndd key 4:24, and then free the members to the 1nfiuence oi": the spring 67,7011 alternate operations of the machine,1'connect the link 69 with the upper arm of a lever 70 pivoted intermediate itsends'ati 1, the remaining arm of the lever being connected to a draft shackle 72 (Fig. 3) having a slot 78 formed therein to embrace a headed stud 74 projectingfrom' and forming anextension of the'pivot Got the tappet 5.

I spring 481 to shiftthe shackle 72 so as to into the path of the actuating stud 6.

theforin shown, theshackle 72 shifts rean 'wardly when theikey 424 is depressed, to :bring' the forward end of the slot into the hringoneend wall of the slot 73 therein, in

' path of the actuatingstud, providing the alternating-member 2with its stud 6 is not already in the positionshown in Fig. 3.

In-such -po'sition,:the stud 6 prevents the shackle Y2 from shifting backwardly, and though theJkeyAQ may be locked in dc pressed position, the counter-restraining members 41'? cannot rock to effective position, owing"; to ,theirconnection through the link 69 and lever 70, with the shackle:

This iarrange nmt prevents the non-add mechanism from-disabling the accumulat ingmechanism when the carriage has posi- $101186, theacolumn for accumulated amounts at; i the printing line.

" 1However,gthe spring 67 will remain unv thereunder, and the shackle 2'2 will retract travels forwardly along the slot '73 in the non-add key 424, and as soon as the der tension due to the depression of the ating arm 1 shifts the alternating member '2 ma counterclockwise direction, and the accumulator axle 400 returns to elevated osition" the restrainin hooks ll? will snap toward the rear of the machine,.to'bring the forward end Wall of its slot. 733 into the path of thestud 6.," 7

Upon, the next return stroke or the. main drive; shaft, during whlch, the actuating arm '1' contacts the-activ'e tappet 5' to swing the alternating member 2 infa' clockwise direction to drive theicarri'age to the left and thereby position the right hand column at the printing point; the actuating stud 6 shackle p72 iuntil'it finally strikes the front end of theslot and draws the shackle forctuwardly to rock the upper arm of the lever 70 rearwardly. The lever through the link 69 swings the restraining members 417 to idle position, further tensioning the drive spring 67. The parts remain in these positions, and hence, the amount next set up on the keyboard, will be printed in the right hand column and will be accumulated on o the counters which will have dropped into engagement with the racks 310 at the end of the forward stroke of the main drive shaft.

The main drive shaft, on its return stroke, will again rock the alternating member 2 i in counter-clocl'rwise direction, during which the actuating stud 6 retreats from the forward end of the slot 73 in the shackle 72,

freeing-the lat-t r and the lever to the ac tion of the tensioned thrive spring 67 which swlngsthe arm 68 downwardly to thrust the restraining hooks 4J7 forwardly to effective position.

The hooks cannot, at this time, take under the counter-supportmg,axle 4200 as the latter is in lowered position, and consequently the hooks abut the axle, in readiness to snap beneath and lock the counters-1n idle position, assoon as the counter-dlsengaging props 319 return theaXle to'its normal ele-' vated position,

The alternating member 2 operater, directly from the maindrive shai't, thus alternately permits and prevents the non-add inechanism from. functioning on successive operations of the machine.

Q viously, it is desirable to prevent depressionof the total and sub-total keys on and 327 when the carriage is at its right hand limit of reciprocation with the left hand column for unaccuinnlated designating numeers at the printing point, as a totaling: operation at that time would print the total of the accumulated amounts, beneath the column of designating indicia. Y

This result is readily efiected by theuse of the mechanism disclosed in U. S. patent to lnlcl arland 880,159, l ebrnary 25, 1908/ lieierring'to Fig; 1, it will be ren'iemberea-l 1 atdepression of either 32'? or B2? rocks the set lever 31'?" to advance the s 32G connectedyto the set lever. @b ions if the slide is locked againstadvancing, the keys cannot be depressed.

Such locking means-includes a latch 619 journaled intermediate its ends on a cross shaftGO mounted inthe side frames. sin angular slot 619" formed in the forward arm of the latch 619 embraces a pin 25d? prejectring from the slide 320. Normally, the pin 25i pression of either key 327 or 327 the slide along that'hranch of the slot 619"- correspending with the path'o'f the slide.

lies in the angle of the slot, and upon do 820 on its advance, causes the pin to travel The rear arm of the latch 6E9 licr path of stud l5? conveniently cai led on one of the restraining members 417. As such member shifts to effective position, "he stud 157 contacts the rear arm ot the late (519 to rock the la -r' and lit that branch of the slot (319 which hes transversely to the path of the Slide 32-1), over the pm 25 9, thereby preventing the advance ot the slide and locking the total and sub-total keys and 327 respectively, a ainst depression.

To enable the ope to disable the alternating member "2, whereby to pr vent the operation and consequent unnecessary wear of the member. when ordinary work 1S to be performed. on the machine, I provide a bolt or stop member (Figs. 3 and slidably mounted in the ng T6 is adapted to rest in e s 77, 78, spaced apart along the bolt, retains, the latter in its outer ineffe tive position, or at its inner effective position wherein it proiects into the path. and just in front of, the tappet 5 when the latter is in its active posi tion at the end of the counter-clockwise stroke of the alternating member. It will be remembered that the tappets 5 or 5 main in their active positions during the return stroke of the i n drive shalt and are held by the actuating arms 1 or 1 againstrocking to idle position until the arms on the succeeding forward stroke, retrac from the active tappet to enable the tensioned spring 13 or H to switch the tappets.

Should the operator adjust the bolt '7 to its effective position while the alternatin I member 2 is at the end of its clo kwise strok at which time the tappet 5 is idle fnll lin-s Fig. 3) no bar .1 will result, as e tap pet on the succeeding counter-clot wise stroke, will contact and cam the bolt outwardly to its ineffective position, after which and before commencing the next foiwvard stroke of the main drive shaft, the operator will replace the bolt in effective position to lock the tappet- 5 in the dotted line position shown in Fig. 8, to hold the opposite tappet 5 in its idle position against the influence of the spring 13, which is tensioned at that time.

The operator, when setting the machine for ordinary work, will manually release the non-add key 424, to enable the spring 481 to restore the restraining members 4H7 to idle position. He will also withdraw the spring-pressed pin 42 (Fig. 8) to allow the spring 481 to return the tabulating bar stops 2018 to effective position relatively to the abutment 2091, and will rotate the turn button 37 to release the adjustable crank 20 to the action of the tensioned spring 39, which, through the operating finger d0, disconnects the couplings 28, 29 and swings the crank rearwardly, thereby enabling the operating finger to retire from its effective position relatively to the line space disabling bell crank 6%, to permit line spacing on successive operations of the machine.

Changes may be made in the form and aringement of the several parts set forth, certain of which may be used alone, as heretofore explained, without departing from the spiritand scope of my invention.
